What family group is Na?
The Alkali Metals
Group 1A (or IA) of the periodic table are the alkali metals: hydrogen (H), lithium (Li), sodium (Na), potassium (K), rubidium (Rb), cesium (Cs), and francium (Fr).
What is Group 13 called?
boron group element
boron group element, any of the six chemical elements constituting Group 13 (IIIa) of the periodic table. The elements are boron (B), aluminum (Al), gallium (Ga), indium (In), thallium (Tl), and nihonium (Nh).
What is the group and period of Na?
Solution : From the electronic configuration of sodium (Na = 11 = 2, 8, 1), we find that there is one electron in its outermost shell (third shell). Therefore, sodium is an element of group 1 and period 3.
What are Group 2A elements?
Group 2A (or IIA) of the periodic table are the alkaline earth metals: beryllium (Be), magnesium (Mg), calcium (Ca), strontium (Sr), barium (Ba), and radium (Ra). They are harder and less reactive than the alkali metals of Group 1A.
Is sodium a heavy metal?
While it is relatively easy to distinguish a heavy metal such as tungsten from a lighter metal such as sodium, a few heavy metals, such as zinc, mercury, and lead, have some of the characteristics of lighter metals, and, lighter metals such as beryllium, scandium, and titanium, have some of the characteristics of …
How is sodium used?
Sodium is used as a heat exchanger in some nuclear reactors, and as a reagent in the chemicals industry. But sodium salts have more uses than the metal itself. The most common compound of sodium is sodium chloride (common salt). It is added to food and used to de-ice roads in winter.
How do you find the group of sodium?
Therefore, sodium is in Group 1 of the periodic table. It is also called the alkali metal group as it contains elements with only one valence electron (alkali metals).
What are periods and groups?
The columns of the periodic table are called groups. Members of the same group in the table have the same number of electrons in the outermost shells of their atoms and form bonds of the same type. The horizontal rows are called periods.
What are Group 3A elements called?
Group 3A. Group 3A (or IIIA) of the periodic table includes the metalloid boron (B), as well as the metals aluminum (Al), gallium (Ga), indium (In), and thallium (Tl). Boron forms mostly covalent bonds, while the other elements in Group 3A form mostly ionic bonds.

What’s new at element?
Element introduces inhibitor testing at its Amsterdam laboratory. Element has expanded its oil & gas testing capabilities at its Amsterdam, Netherlands laboratory with the introduction of corrosion inhibitor testing.
Where is sodium found in nature?
Although sodium is the sixth most abundant element on earth and comprises about 2.6% of the earth’s crust, it is a very reactive element and is never found free in nature. Pure sodium was first isolated by Sir Humphry Davy in 1807 through the electrolysis of caustic soda (NaOH).
Is sodium reactive in nature?
Sodium, like every reactive element, is never found free in nature. Sodium is a soft, bright, silvery metal which floats on water. Decomposition in water results in the evolution of hydrogen and the formation of the hydroxide. It may or may not ignite spontaneously on water, depending on the amount of oxide and metal exposed to the water.
